Synchronization of a unified chaotic system and the application in secure communication. (English) Zbl 1005.37012
Summary: This Letter further investigates the synchronization of a unified chaotic system via different methods. Several sufficient theorems for the synchronization of the unified chaotic system are deduced. A scheme of secure communication based on the synchronization of the unified chaotic system is presented. Numerical simulation shows its feasibility.
